I need to get value from radio button in angular. Suppose to have this html code:

 <label class="radio-inline">
   <input class="form-check-input" type="radio" [(ngModel)]="dog" name="gob" value="i" [checked]="true" (change)="onItemChange(item)"/>Dog
 </label>
 <label class="radio-inline"> 
   <input class="form-check-input" type="radio" [(ngModel)]="cat" name="cat" value="p"  (change)="onItemChange(item)"/>Cat
 </label>

In my ts page I need to get the value of radio button like

dog.value

My purpose is:

1. Set default cheched to first radio button
2. Get the value when I click on radio button

Anyone can help me?

Answer 1

You can bind the data of radio button. Just add the value for radio button and change in the ngModel

html

<input class="form-check-input" type="radio" value="dog" 
[(ngModel)]="dog.value" name="gob" value="i" [checked]="true" 
(change)="onItemChange($event.target.value)"/>

ts

onItemChange(value){
   console.log(" Value is : ", value );
}
